Introduction

WebAssembly (WASM) is revolutionizing serverless edge computing by providing near-native performance with sandboxed isolation. At Votion Cloud, we've engineered a runtime that embeds a WASM virtual machine directly into the Kubernetes edge node, eliminating container overhead while preserving security boundaries.

Architecture Deep Dive

The Votion Cloud edge runtime leverages a lightweight WASM virtual machine embedded within a Kubernetes sidecar. Each edge function runs in its own linear memory space, with system calls mediated by a capability-based host interface. This design enables sub-millisecond cold starts and deterministic resource accounting.
